IMPROVElVlNT IN VENTILATING MILK-CANS.

fluvia shall be removed by the agitation of traniportation, and the nature of my invention will be apparent as I describe it.

Figure 1 is views of a milk-can top with my device attached to it. Figs. 2 and 3 are modications of it, and Fig. 4 is a further modification of it.

In Fig. l, A is the .can-top, and B an upright tube in it," seen` bya sectional view. The l The lower one, B', has two diaphragms, C and C', attached "to it, as has the upper removable porc tion, B, also two partitions, Gmand G.

rlhe object of thispdivision in this and subse- `quent figures is toenable the parts to be sepa rated and cleaned, and of the partitions or segments, is to allow air to go in. and out, but the milk to be retained. i

" In Fig. 2, seen as `the `last figures both in perpendicular section and also by a view looking downon thetop of it, is amoditication by which the tube holding the partitions is not dividedtransversely but perpendicularly, and it slipsout beneath the can-cover A. The diaphragm G locks into the righthand half of the tube, while a bayonet lock, N, inr the "left-hand half holds the divided tube in the can-top. i

In both forms of Figs. l and 2 it will be noticed `that muchof my invention relates to one or more tubes'and` tothe partitions in the tubes or tube; yand in Fig. 3 another modication of these tubes and partitions is seen, where D is part of the tube below the cancover A, which cover at E has a large hole in it, and the part of the`cover included in the tube D marked D vserves as a partition. Above, in the removable part, is the continuation of the tube D, (marked D,) while .the

. cap-cover serves asa diaphragm, and has the holes F outside of the tube D into the space between D and D". It is readily seen how it can be separated and washed. The ventilator-cap handle Gis also clearly seen; but the large cover-handle is not shown inany of the figures.

In all the figures so far it has been the de# sign to use two ventilators to each can, if de.-

sirable; but one, and larger, 'I also use, I as seen in perpendicular sectional outline in Fig. 4, `Whereinfthe removable portion ofthe tubing atthe bottom, below the cover A, is a series of holes, I-I, and also a diaphragm, with one hole, I, in its center. In the cover, which serves as apartition, are the series of holes J. Then comes the removable upper part, with a partition, with the central holes, K, and th `top open, as seen at L.

Various other similar modifications might be shown, but are, with the advantages and `uses of my invention, apparent to those skilled inthe artto which it appertains.

I claimy 1. A ventilator inserted into the `cover or other part of the top of a can, composed ofV the tubular part or parts B and D and the transverse section or sections C, substantiallyas set forth.

2. The section or sections C, when the per- -forations or series of holes F or equivalent
